ABSTRACT
@#Objective To explore the prognostic value of serum cystatin C (Cys C) in patients with congenital heart disease-associated pulmonary arterial hypertension (PAH-CHD). Methods A retrospective cohort study was conducted on adult PAH-CHD patients who were hospitalized for the first time in the First Affiliated Hospital of Xinjiang Medical University from January 2010 to January 2020. The serum Cys C and other related data of patients were collected. The median follow-up time was 57 months. The main end event was all-cause death. According to the prognosis, the patients were divided into a survival group and a death group. Cox regression was used to analyze the risk factors for all-cause death in patients with PAH-CHD. Results A total of 456 patients were enrolled, including 160 males and 296 females, aged 38.99±14.72 years. The baseline data showed that there were statistical differences in resting heart rate, serum Cys C, creatinine, NT-proB-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT), high-sensitivity C reactive protein (hs-CRP), New York Heart Association (NYHA) cardiac function classification and serum potassium between the survival group and the death group. Univariate Cox regression analysis showed that serum Cys C, NT-proBNP, hs-cTnT, creatinine and NYHA cardiac function classification were related risk factors for all-cause death in patients with PAH-CHD. Multivariate Cox regression analysis showed that serum Cys C (HR=3.820, 95%CI 2.053-7.108, P<0.001), NYHA grade Ⅲ (HR=2.234, 95%CI 1.316-3.521, P=0.010), NYHA grade Ⅳ (HR=4.037, 95%CI 1.899-7.810, P=0.002) and NT-proBNP (HR=1.026, 95%CI 1.013-1.039, P<0.001) were independent risk factors for all-cause death in patients with PAH-CHD and had a good predictive value. Conclusion As a new cardiac marker, serum Cys C can predict all-cause death in patients with PAH-CHD and is an independent risk factor.
ABSTRACT
Objective:To assess the association between maternal smoking, passive exposure to smoking, or paternal smoking in the first trimester and the risk of congenital heart disease (CHD) in offspring.Methods:A meta-analysis was performed on selected case-control studies on parents in the first trimester and CHD involving CHD patients regardless of age or ethnicity, after searching PubMed, Web of Science, Cochrane Library, CNKI, WanFang Data, and China Biology Medicine up to April 2021. The main outcome was CHD confirmed by cardiac ultrasound or cardiac surgery and the quality of included studies was assessed using the Newcastle-Ottawa Scale (≥4 scores). Statistical analysis was carried out using RevMan5.4 software and heterogeneity was determined by Q test combined with I 2 test. In accordance with the heterogeneity test results, the appropriate model (random or fixed) was selected. Subgroup analysis was performed according to the subtype of CHD. Potential publication bias was assessed by funnel plots. Results:A total of 35 studies involving 38 125 subjects were included. The pooled results showed that the risk of CHD in offspring born to mothers who were active or passive smokers in the first trimester was 1.20 ( OR=1.20, 95% CI:1.15-1.26, Z=8.15, P<0.001, I 2=35%) and 1.95 times ( OR=1.95, 95% CI:1.70-2.24, Z=9.52, P<0.001, I 2= 69%) that of non-smoking mothers. The risk of CHD in offspring of fathers who smoked in the first trimester was 1.88 times higher than that of non-smoking parents ( OR=1.88, 95% CI:1.49-2.36, Z=5.39, P<0.001, I 2= 69%). Subgroup analysis indicated an association between active maternal smoking in the first trimester and an increased risk of atrial septal defect ( OR=1.41, 95% CI:1.03-1.92, P=0.030, I 2= 71%) as well as between maternal passive smoking and increased risk of atrioventricular septal defect ( OR=1.76, 95% CI:1.37-2.26, P<0.001, I 2= 11%). Conclusion:Maternal and paternal smoking in the first trimester may both increase the risk of CHD in offspring.
ABSTRACT
Diplomates certificated by National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM) are needed to be recertified every four years. The certificate will be valid after 60 points of provided professional development activity (PDA). The different validity status of NCCAOM certificates, ways of participating continuing education and the requirements of PDA points including core competencies and professional enhancement (PE) are introduced in this paper.
ABSTRACT
<p><b>OBJECTIVES</b>To evaluate the psychological quality and its influencing factors of mine rescue staff.</p><p><b>METHODS</b>A total of 310 on front line rescue staff from the mines in Tangshan were sampled by random cluster sampling method.Our own designed measurement tools for psychological quality, including Eysenck personality questionnaire (EPQ), attention test scale, willpower test scale and reactive agility test were used to investigate the psychological quality of mine rescue staff. All tests were conducted in quiet state.Other information including age, length of service for rescue, sex, education, smoking and drinking, and so on were collected at the same time. The mood and influencing factors on psychological quality of the rescue staff were also analyzed.</p><p><b>RESULTS</b>The personality traits of mine rescue staff are close to the national norm.0.6% (2/310) staff showed weak willpower.20.7% (64/310) staff had unstable mood. The E and N factor scores in 20-29 years old group (12.7 ± 4.3 and 12.1 ± 5.1) were higher than 30-39, 40-49, 50-59 years old groups (E factor scores:11.4 ± 3.9, 10.6 ± 3.7 and 10.7 ± 3.9; N factor scores:11.0 ± 5.1, 9.4 ± 4.9 and 6.3 ± 3.4, respectively) (FE = 4.28, FN = 11.35, all P < 0.01) . The L factor score in 40-49 and 50-58 years old groups (13.0 ± 4.2 and 14.8 ± 3.6) were higher than 20-29 and 30-39 years old groups (11.5 ± 3.8 and 12.2 ± 3.8) (F = 6.08, P < 0.01) . Multivariate analysis found that the psychological quality of mine rescue staff was mainly influenced by the length of service (β'E factor = -0.12, β'willpower = -0.12), the amount of participating rescue (β'P factor = 0.12, β'N factor = -0.14), alerting duty (β'L factor = 0.16, β 'error number of target tracking = -0.161) , daily training (β'attention = 0.22,β'total number of aimed at the test = -0.18) and life events (β'N factor = -0.14,β'L factor = 0.13,β'correct number of target tracking = -0.18).</p><p><b>CONCLUSION</b>The mine rescue staff had high level psychological quality, length of service. the amount of participating rescue, and life events in the year effect the psychological quality of mine rescue staff.</p>

<p><b>OBJECTIVE</b>To prepare quercetin nanostuctured lipid carriers (QT-NLC), and detect their physicochemical properties.</p><p><b>METHOD</b>QT-NLC was prepared by emulsification ultrasonic dispersion method, and the optimum prescription was screened out by orthogonal design. Transmission electron microscope was used to observe QT-NLC morphology. Granulometer was applied to determine zeta potential, particle size and distribution. DSC was adopted for phase analysis. Centrifugal ultra-filtration method was used to determine entrapment efficiency. Dialysis method was adopted to detect drug release in vitro of preparations.</p><p><b>RESULT</b>QT-NLC prepared under optimum conditions was mostly spherical grains, with the average particle size of (175 +/- 25) nm, which were distributed evenly, and zeta potential was (-23 +/- 0.3) mV. DSC results indicated that the drug was dispersed in nano-particles in a non-crystalline state, with an entrapment efficiency of (95.43 +/- 0.23)% and a drug-loading capacity of (2.38 +/- 0.24)%. The in vitro drug release was 32.2% in 2 hours, which was followed by a sustained release.</p><p><b>CONCLUSION</b>Emulsification ultrasonic dispersion method is applicable for preparing QT-NLC, as nano-particles are distributed evenly, with good reliability. This processing technology is safe, reliable and highly reproducible.</p>
